This invention relates to grain separators y and has for an object ltheprovision of Sa machine by means of which smut grain and garlic or wildonion ma be separated from l good wheat grain and t e juices of thegarlic absorbed;` before the protecting coat of thegrain is broken, sothat danger `of contamination of the inner food substance when the grainis und,`will be avoided.

Another o ject of the invention is the provision of agrain separatorhavi noyel means for separating the garlic hilis and the smut dust 'andother extraneous matter from the wheat grains after l,the garlic has lbeen crushed and 'its juices absorbed.

A further. object of the invention isthe provision ofa machine which inaddition to the above mentioned and other advanta s, combinessimplicity, ofy construction,

e ciency, and will separate a maximum amount of grainin a relativelyshort time at a minimum costa With the labove and other objects in view,lthe invention'further, includes the following novel features anddetails f construction,

to be hereinafter more fully described, illustrated in theaccompanylndrawings and pointed out in the appends4 claims.

In the drawings Figure 1 is a slde elevation of a separator constructedin accordance with the invention.

Figure 2 is an end view of the same. Fi ure 3 is a sectional view takensubstantlally on the line 3-3 vof Figure 1.

Figure 4 is an enlarged fragmentary section on the line 4-.4 of 2.

Figure 5 is a--similar view on the line Y 55 of Figure 4.

Figure 6 is a like view on the line` of F1 3. f-

J rring t0 the drawings in detail wherein like characters ofreferencedenote corresponding parts, the reference character 10indicates the frame of the machine which may be of an suitableconstruction or design and which supports in any suitable manner, a mainhopper 11 which is designed opposite sides of the ho per 11 areauxiliary `hoppers 12 and these stv mentioned hopto hold the material tobe separated.` -Atpers are designed to hold a low grade of Hour orsimilar material. The lower' ends of the hoppers 12 are substantiallyclosed by pressure rolls 13 which are provided with a facing 14 ofrubber or other compressible material. This facing is of a character topermit` of the passage of wheat grains therebetween without in- ?'curyto saidgrains, but which willl crush smut grains and'garlic or wildonion pass- .l The material from the hopper 1L is fedi to the rol-ls 13-by a feed roll. 19 which is spirally grooved as shown at 20 and theperiphery of this roll is in contacting engagement with a regulatingplate 21. The plat 21. is pivotally mounted as shown at 22 and hasextending therefrom an arm 23 upon which is adjustably mounted a weight24, so that pressure of the plate 21 upon the roll 19 may be accuratelyregulated'.

The shaft of one of the rolls 13 has secured thereon a grooved pulley25, While the shaft of the roll 19 carries'a grooved pulley 26 and thesepulleys are connected by a belt 27. Also secured upon the shaft of oneofthe rolls 13'is Aa pulley 28which is mountedin suitable bearingssupported 4by the frame 10. This shaft has mounted upon 'its oppositeend fast and loose pulleys 32,

the fast pulley receiving power from 'any suitable source. 1

As thus Jfar described, the rolls 13 and the roll 19 will be operatedfrom the shaft 31 and as the rolls 13 pass beneath the lower lends ofthe hoppers 12, these rolls are dusted with fiour vfrom the hoppers.The' wheat grains and arlic are fed from the hopper 1l by the ro l 19,the plate 21.being adj usted to feed suflicient material to practicallyform ^one layer upon the roll. The perfect grain will' pass uninjuredbetween the rolls 13, while/,the smut grain will 'be crushed by saidscrape therefrom the paste formed by theA I. powder and the absorbedgarlic juices. If

desired, these scraper blades may be adjustably mounted. The chute 34extends downward outside of the side -members of the frame 10, whilethe. chute 33 extends outward at one end of the frame andthe materialpassing through these chutes may be directed .into suitable receptacles(not shown).

The rain and garlic hulls passing between i the rol s 13 fall', downwardupon an inclined is mounte ter the screen 43 to permit of the passagethere-.

channel-shaped chute 36 which for 'swinging movement in the frame,hanger rods 37 being provided for this purpose. The chute 36 is adaptedto be swung longitudinally so as to provide a shaker or agitator and forthis purpose there is provided an eccentric 38 which is mounted upon ashaft 39 and which 'has its arm 40 pivotally lsecured to the upper endof the chute 36 ,as shown at 41. The material falling upon the chute 36will thus gravitate down the chute, the4 motion of the chute aiding inthis movement.

The chute 36 is provided with spaced openings 42 and secured above` oneof these openings and extending transversely of the chute is a screen43, while. a' similar screen 44 is positioned over the other opening.The side walls of the chute 36 at each end of the screen 43 are rovidedwith openings 45 for the assage oan endless 'screen 46, the lat- Eeingspaced a 'suiiieient distance above transversely betweenof a singlelayer of .grain and'to also permit the crushed garlic to pass beneaththe screen 46. This last mentioned screen is mounted upon rollers 47which are supported iny suitable bearings 48 at each side of the chute36 and the shaft of one of these rollersL has secured thereon a groovedpulley 49 which is driven by a' belt 50 and a pulley 51 mounted upon theshaft 31. The belt ,50

passes over 'an idler pulley 52.

Located above the endless screen 46 and extending transversely acrossthe chute 36 and through one of the side walls of the chiite as shown at53 is the lower end 54 of a.l conduit 55.- The'- upper end of thisconduit is in communication with the casing 56 j of a suction fan uponwhose shaft is mounted a pulley 57 and this pulley is driven by a belt58 which passes around a pulley 59 fast upon the shaft 31.

- Vhen the grain and garlic reach a position upon the screen 43 beneaththe endless screen 46, the suction fan will raise the garlic hullsupward against the under face of the screen 46. This is due to the factthat the removal of the garlic juices has lightened and flattened thehulls so that they are considerably lighter than the grain. lic hullswill thus becarried transversely of the chute or to the lleft of Figure3 of the drawings and when they vreach a position within the extendedportion 53 of the mouth lof the conduit they will be beyond the edge ofthe chute 36 and out of the path of suction of the fan. The garlic hullswill then drop into the mouth of a chute 60. The grain will continue togravitate downward toward the outer end of the chute 36 and when passingover the screen 44, hulls or The garother relatively small matterwhichhas not the bottom of the agitator, suction meansv positioned above theconveyor screen to hold. relatively light material in contact with saidconveyor screen and convey said material beiyond the agitator, meansoutside of the agit-ator to relieve the suction and means to Aoperatethe conveyor screen.
